The new and improved Dreach is plenty good. Having extra range has always been a luxury and now with a -10% threat inaddition is a cause for sheer joy.

The new intensity now offfers 70% non interruption to not only AOE spells but all destruction spells. If you have this and the FM glove -50% interruption to searing pain, your SP spell will be 100% non interruptable. I feel that this talent is kinda overpowering but i welcome it. LOL

This is a pure damage buff. Really good to have.

Considering this is a 25pt talent, its still a luxury to have in PvP mainly against Firemages and Shadow Priest only. In PvE raids, this talent will help warlocks to survive longer in combat against strong Shadow and fire mobs. Its usage is indeed very limited for my liking.

Given that this spell has a proc of 30% only. It makes it a luxury to have to a certain extend, however this talent is still very worth spending 3 points on. Given the number of spells it can be triggered off.

AN instant cast with very high AOE damage and 100% chance to AOE stun targets for 2sec. Very worthy of being the final talent of the destruction tree. This is a very interesting spell and a must have if going deep into the destruction tree.
